The invention discloses a method of processing a lignocellulosic material using an alkaline delignification agent. The present invention relates to a method for obtaining sugar and lignin fractions from lignocellulosic materials and to a method for producing fermentation products using the sugars obtained from the lignocellulose. In particular, the present invention relates to a method for improving the sugar yield in the enzymatic hydrolysate by introducing a pre-treatment step of hydrothermal hydrolysis and an alkaline delignification step. 本发明涉及用于由木质纤维素材料得到糖和木质素部分的方法和用于使用得自木质纤维素的糖类生产发酵产物的方法。具体地，本发明涉及用于改善酶促水解产物中的糖产率的方法，通过引入热水水解的预处理步骤和碱脱木质化步骤来进行。
